You're crying over milk that isn't spilled yet. Wait to see the meta before crying OP. This is a 4 mana card that needs other cards played ahead of it to be worthwhile. It does combo well with the goons it is a part of; however, Paladin is the one with buff all the cards in your hand. This will rely on cards specifically buffing it for it to be good (and most of those buffs are buff a random minion in your hand). Not nearly as strong/powerful as Call of the Wild was that truly needed a nerf. But I would bet that some more smorcing will go on with this card (either that or really valuable trading).

So this is basically pre-nerf Keeper of the Grove, but without the mana crystal option. It also has synergy with Leokk and other cards that boost damage for minions. So overall it seems like a great tempo play, but not broken. I would rate it 8/10 for constructed and 9/10 for arena.
